I don't think it's the case that a complex/chaotic macro system like the stock market or a bee hive or the body's immune system (or Ned Block's Chinese nation; perhaps they all WERE having a macro-thought) is ungrounded in quantum / relativistic effects. Drop a bee hive and it accelerates towards the earth at 32.2 ft/sec/sec. The warp of gravity still rules. Put it in the gas chamber with Schrodenger's cat and the bees, along with their hive intelligence, are now in something like a quantum superposition (perhaps). If the rate of gravity acceleration were different or if quantum events were different, the dynamics of these systems would be different. So the quantum / relativistic effects may be more than something in the "noise bin" of a complex system. The complex system's behavior is partly determined by elemental gravity physics and quantum physics, and yet it also appears to be determined by relationships unique to the complex, recursive dynamic system, relationships that are not strictly reducible to gravity and quantum physics as we now know them. I've read that our quantum laws and relativity laws may actually be emergent phenomenon in themselves, along with time, space and mass (the latter emerging from Higgs field boson interactions). Some thinkers speculate that these laws still do not touch the bedrock of reality, that there are even more fundamental physics from which these emerge. We can perhaps conceptualize a chain of emergence: chemistry emerging from quantum physics, earthly and celestial mechanics emerging from relativity / gravity laws, geology and biology emerging from these, humanity emerging from these, sociology and psychology co-emerging from the animal realm. At each level, something has 'self-organized', something has taken the better innovations that randomness allowed, breaking the deadening symmetry of stuff like crystal structures and yet retaining enough of their structure to allow reproduction, as with clay. Somehow these arrangements retained the innovation as to allow new characteristics and new integrations (akin to natural selection? Natural selection being a huge example of chaos-driven, self-organizing emergence?). We might judge some of these "new, irreducible characteristics" to be subjective, based on our needs and what we want to see. If true, that might say something about the fundamental role of consciousness, and not just imply that 'we're just seeing things'. But I'll leave the dualism axe aside for now. The math and systems people appear to have identified objective characteristics, or at least some candidate metrics for future research regarding system emergent behavior (just as they have done amazing stuff with chaotic processes, which are really just the other side of the coin from emergent phenomenon, e.g. fractal relationships, period doubling, attractors, etc.). They seem to be discussing potential elements and metrics for emergence such as organization, connectivity, independence and diversity, as well as the threshold conditions for emergent behavior to appear. I hardly understand the mathematic formalisms, but I've read of some interesting paradigms regarding "order ranking" based on shape interactions, shape interactions with a time dimension, and shape, time and heritable instructions (presence of information retention / reproduction mechanisms). A lot of people seem to think that this goes well beyond supervenience to quantum laws and/or relativity laws. The following is a SWAG, but I would posit that emergent relationships and effects have something to do with the 'information state' of the complex system, the level of entropy and information-meaningfulness of that entropy, the 'logical depth' of the system (assuming that I roughly understand that concept). I'm wondering if information will turn out to be a "state space dimension" that helps us realize the difference between galaxies, quarks, and mid-level / highly complex things like life forms. Galaxies, down to the level of suns and planets and asteroids, don't need much information (relative to their size and mass) to specify their internal dynamics; so much is repetitive. Ditto for quarks, baryons, and their strange, wave-like relationships in the micro world. But even a bacterium needs a whole lot of information to specify its dynamics and relationships. Perhaps information-density at some threshold changes the rules (or better put, will ultimately require a more flexible and complex "theory of absolutely everything" that will account and adjust for the information dimension). Perhaps those seemingly unique rules that our mathematicians are now studying regarding chaos and emergence patterns in abstract state-spaces are ultimately driven by there being such an information dimension, with certain systems having an information richness that brings these seemingly unique rules into play. There does appear to be progress in objectifying the notion of information. And what then of randomness? Emergence requires it for the creation of order; chaos assumes that it 'emerges', if you will, in certain state-transitions according to some high-order descriptive patterns. Does it break in from the quantum world, or is big-system randomness something different? Even if not related, is there something amidst the quantum randomness and weirdness that we observe which actually allows higher order effects in high-information density / "meaningful entropy" states (while still maintaining a random dimension in the micro world)? Something akin to hidden variables, something to do with non-local effects and phase entanglements? If so, then perhaps there is supervenience, but to patterns in the quantum dance that we presently do not see? Yikes, I've tried to let the mind run, but is seems to have tripped. It's popping out too many questions, not enough answers! Enough for this evening, time to cool the neurons, calm down the mental state-space. We don't need another 'What the Bleep' here!

H20310401, Some thoughts, if I may. Quote:

But at some point, "true random" effects from the quantum world would derail even this train. These would be relevant in those instances, however rare, where our macro-world is influenced by a tiny quantum event (akin to Schrödinger's Cat awaiting its quantum throw of the dice). With most things and events in our world it doesn't matter, but there are non-linear systems which are very sensitive to initial conditions, which greatly amplify the slightest perturbation; thus, at some point a non-predictable quantum event will change the macro world. Also -- Heisenberg uncertainty is a prime example, perhaps THE prime example, of the fundamentally unknowable at the quantum level, the inherent "limit of knowledge" about nature. Quote:
However with randomness, I see the universe becomes more random as we reach the quantum side, thus more linear. (ex. entanglement, because particles acting the same way are not very chaotic, but at the same time they are in undefined states) Perhaps there's some difference between unknowability, as required by Heisenberg, and randomness, which appears to drive much of what we can know about a quantum thing (or more precisely, about our observations of a quantum thing). We can't challenge the unknowable (e.g. the Heisenberg pairings such as location and momentum); but as to randomness, arguably there could still be more pattern mixed in with the noise than we have detected to date, as per the late, great David Bohm and his hidden variable ideas; although some randomness would always remain. As you imply, phase entanglements, although relatively weak, may conceivably impart some order amidst sets of quantum particles that have interacted and remain within some proximity range. Quote:

Without the uncertainty, everything goes zero-D!!! Since the extra dimensions of M theory supposedly just go around in tiny circles, we arguably can't explain away inherent uncertainty as the result of unperceived but effective dimensions (think about the 3D being interacting with the 2D plane world in Flatland). These dimensions wouldn't seem to offer an alternate route from point A to point B, or a way to hide part of a hyper-body from our universe. So the fuzziness and jumpiness and uncertainty of quantum particles arguably isn't because they're ducking into hyper-spaces then coming back to our space, or keeping parts of themselves hidden outside of our space.

| Re: Neurons "If you knew the starting condition and had a limitless computer, you could do the simulation before the reality actually occurred, and know the numbers, however random they are relative to each other." Ah but I don't think it matters. See, if actuality is monistic can it change? Do we need a mind and perception in order for there to be change and conditions? I think so, therefore, the starting condition is the same throughout all of actuality; if you were to display actuality as being in sequence to time, which I doubt. When time becomes a factor, presented when there is consciousness, then relation is possible. I have a theory about this. Maybe in actuality in order for time to be of its "monistic essence" it does not flow, but is in instances, and no instance is direct correlation to another. So we can say that it is purely random, yet also, completely linear because all instances imply any other instances exactly, intrinsically when reality gets involved. And with reality, we have perception, so time can flow. It is what it is, but not actually 'flowing'. Flow is a product of potential, and in a durative sense it would be causality that is the potential, to me anyways. Edit: I'm glad we both agree with linear being random , people usually don't see that.Edit 2.0: Detailed response when I'm more awake I'm kinda deep in thought for other stuff right now

| Re: Neurons
PaulH, These are truly questions on the outer limits of what the mind can do (or what my mind can do, anyway). There appears to be reason to postulate an ultimate reality that unifies and subsumes events and relationships on all levels of scale; and to believe that the unification theme of this reality has to do with a "beefed-up" concept of information. Our physical sciences are increasingly coming to appreciate the notion of 'super information' (e.g., through under-development concepts of the "computing universe", the "digital universe", etc.). Humankind may come to understand, abstract and empirically describe this bedrock reality, and perhaps see it as another dimension, just as time was acknowledged after Einstein to be as much a dimension as the big 3 space dimensions. We may come to appreciate the ontological significance of 'super information' sometime in the future -- perhaps generations or even centuries into the future. That's my SWAG. As to whether randomness ultimately exists -- wow, another question that's probably left to future generations. If it IS irreducible, then we will be left with a dualistic universe, something like the old Zoroastrian view of a universe of competing and blending influences from opposite, ultimate poles of good and evil. Except, it will be a universe of order and anti-order, information and anti-information (i.e. true indeterminate randomness). As to whether and how conscious subjectivity would make sense in a web of ultimate universal order eternally clashing with the forces of infinite chaos -- again, we're out on the limits of thinking. Or at least the limits of my own thinking ability! It makes me dizzy, like when reading the Upanishads.Still, this 'out to the edge' discussion has been quite interesting, and will be useful in pondering the more "limited" philosophical questions such as human freedom, the meaning of life, and so on. I.e., limited but still unanswerable -- as you imply, this is philosophy, after all! Regards,Jim G. Quote:

| Re: Neurons
H20310401, Just for fun, I've made some very raw, extremely speculative, off-the-top-of-my-head, bordering-on-who-knows-what replies to your thoughts. If interested, here they are: Well, as I asked in my latest reply to PaulH, is randomness an ultimate reality? if so, monistic reality is toast -- but read on, maybe not . . . From a personal, quasi-spiritual perspective, I'd like to believe that the universe is ultimately monistic, that randomness is ultimately deterministic even if temporally uncorrelated; just an illusion to an imperfect consciousness. But what if randomnesss and order are universally essential, opposite poles, like the Zoroastrian eternal opposites of good and evil? Let me imagine them spinning off flows which meet and mix and interact. Eventually these flows blend. And perhaps these blends lose all movement and energy once completely blended. The universe would thus be ultimately headed for heat death and stillness (the recent discovery of dark energy being another hint that this is where it's all heading). Unless -- unless consciousness somehow flourishes, somehow survives, and somehow inspires the use of orderly analytical processes to come up with a universe "game changer", along the lines of Frank Tipler's plan in "Physics of Immortality". OK, Tipler's plan per se won't work if the current dark energy expansion scenario precludes a "big crunch". But what if some other cosmic shortcut is discovered some day that allows some huge energy and information harnessing, thousands of years from now, as Tipler imagines in Physics of Im. ? Consciousness then makes a fundamental difference to actuality. The dualism that was going to become a monism of nothingness becomes a monism of somethingness and being, thanks to consciousness as an ontological game-changer. Quote:

How about the need for balance. Balance can be self oriented, but only through temporal being; thus ruling out actuality not being in balance. Only when reality comes into the picture does it seem like a form of balance is trying to occur, perhaps symmetry, which in itself requires perception. So what can come out of actuality? It is nothing, but in that, everything is able to come out of it. Even though actuality would be absolute, linear, nothing, blah blah blah... we can say that one part of it implies another part of it. Therefore absolute order. But also, pure randomness in that if infinite, there is no defining point to work with. Order cannot be implied by actuality's own sense, since it is not anything of its entirety. But say we broke it up, a piece of it is still underlyingly implient to any other piece of actuality but no longer in the picture of the entirety of the actuality thus a piece of randomness seeking the whole order. A piece of actuality is still bound to actuality and is actuality by intrinsics and is still like a piece of nothing, but now that it is defined, because its finite, it will automatically have the potential, thus cause, and perception. So a piece of actuality is reality in that actuality only implies itself through its own entirety. I mean, perhaps there are sequences that are random from this actuality to make a reality, in that picking out a piece of actuality is completely random in that no cause can be ascertained for it. If a piece of it implies any other then all pieces must be the same potential. Until the piece is chosen does the piece become of potential, and in that, perspective. And since the piece in its own entirety is absolute but a random piece of actuality, it is not the entirety of actuality and absolute only intrinsically to actuality, and therefore a little off from actuality in its potential, in that potential is now given to the piece(reality). A rule can be made from this. Potential is not defined through intrinsics. ![]() Quote:
Makes sense, we could label information as cause/potential. hyper-effect ![]() I'll keep that in mind and yes you're understanding it right. And yes I think by saying a system has potential means the system would automatically allow for consciousness.

In a recent post, I have had the following response from hermes. Quote:
Therefore, emotions as defined by 'The Online Free Dictionary by Farlex' states: "In psychology, emotion is considered a response to stimuli that involves characteristic physiological changes—such as increase in pulse rate, rise in body temperature, greater or less activity of certain glands, change in rate of breathing—and tends in itself to motivate the individual toward further activity. Early psychological studies of emotion tried to determine whether a certain emotion arose before the action, simultaneously with it, or as a response to automatic physiological processes. In the 1960s, the Schachter-Singer theory pointed out that cognitive processes, not just physiological reactions, played a significant role in determining emotions. Robert Plutchik developed (1980) a theory showing eight primary human emotions: joy, acceptance, fear, submission, sadness, disgust, anger, and anticipation, and argued that all human emotions can be derived from these. Psychologists Sylvan Tomkins (1963) and Paul Ekman (1982) have contended that "basic" emotions can be quantified because all humans employ the same facial muscles when expressing a particular emotion. Studies done by Ekman suggest that muscular feedback from a facial expression characteristic of a certain emotion results in the experience of that emotion." A correlation of the definition and the concept of cause and effect, suggest that 'emotion' is just a word we attach to explain the reaction to the combination of external and internal stimuli of neurons in the brain, and the awareness that brain matter has constitute for the way we feel during each emotional state. On the other hand, a computer can be programmed to simulate the brain's activities. The simulation will also produce identical states of emotions to that of the human brain. However, the difference will be that the computer simulation is a program and would not posses feeling because a program is not material, and therefore, not aware of its reactions; while the human brain follows its program faithfully and is aware of it. All hopes for a computer to have true emotions - as we defined - is not loss. Scientist may one day design a computer with a physical - as we define - program. Sorry to sound so long winded, but it is necessary at times for some people to grasp your concepts, and sometimes they still do not. Hope that spark some imagination. |

| Re: Neurons Food for Thought What is the difference in consciousness between man and computer? We usuallly associate consciousness and behaviour. Bear in mind, consciousness does not effect behaviour; orderly chaotic neurons do. Consciousness is only the observer. Because a computer functions differently and compose of different materials and design, Alone that does not suggest consciousness. Is there consciousness in all matter?
